I have the following setup:
Apache/1.3.27 (Unix) - Linux mod_ssl/2.8.14 (using mm) OpenSSL/0.9.6b PHP/4.3.1
SSL and non-SSL sites are running on the same instance of Apache.
While working on a PHP-based form I noticed that on random occasions POSTed data will completely disappear.. as if it was the first time the user visited the page. After days of trying to resolve the issue, I ended up just writing a simple form (see below). It was still intermittent though but I began to notice a pattern. If I uploaded the file (overwriting it) then the POST data disappeared. BTW.. this was on the SSL-enabled virtual host. When tested on the non-SSL-enabled virtual host (running under the same instance of Apache) I did not run into the problem. I also tested out previous scripts on the SSL-enabled host and, to my shock, discovered the same problem!
Tonight I have finally been able to re-create the problem. I can submit data into the form (the test form below just posts to itself and displays the posted data, along with the POST array) numerous times and the data will remain the same or change if I change it. However, if I "touch" the file or overwrite it, the next time I submit the form, the POST data is gone. Nothing. Ziltch. I can consistently duplicate this on the SSL-enabled host but it never happens on the non-SSL-enabled host, leaving me to believe it may be a problem with mod_ssl or some program it's compiled against (mm, perhaps?). I looked into any cache options but the only one, SSLSessionCache, is not set, so I assume it's set to the default: none.
Has anyone encountered this problem and have a solution?
Below is a sample script which exhibits the problem. You can test it by following the steps:
First fill out the form and sumbit. Wait about a minute and either 'touch debug.php' or overwrite it. Then resubmit and everything will clear out. I'd appreciate it if some of you could test this and see if you get the same result.
-----BEGIN debug.php----- <?php
// Start a user session session_start();
print_r($_POST);
?>
<!--<html> <head> <title>Debug</title> </head>
<body>
<form method="POST"> <input type="hidden" name="submit" value="1">
First Name: <input type="text" name ="first_name" size="16" maxlength="32" value="<?php if ($first_name != "") { echo($first_name); } ?>"><br>
Last Name: <input type="text" name ="last_name" size="16" maxlength="32" value="<?php if ($last_name != "") { echo($last_name); } ?>"><br>
Phone: <input type="text" name ="phone" size="16" maxlength="32" value="<?php if ($phone != "") { echo($phone); } ?>"><br>
Fax: <input type="text" name ="fax" size="16" maxlength="32" lue="<?php if ($fax != "") { echo($fax); } ?>"><p>
<input type="submit">

</html>--> -----END debug.php-----
